A dead crow found in Wayland has tested positive for the West Nile Virus, Massachusetts Department of Public Health officials said today.
The virus can cause serious illness and even death in humans and is most often transmitted by bites from infected mosquitoes.
Sixty birds have tested positive for WNV statewide in 2008, up from 43 all year in 2007. There has not been a human case of the virus this year.
Despite the colder weather, officials say residents should still wear insect repellent when walking in wooded areas and drain standing any standing water on their property to deny Culex mosquitos -- the type the spread West Nile -- their favorite breeding ground. Mosquito season does not end until there is at least one killing frost.
Officials are also urging residents to continue reporting dead birds to the DPH by calling 866-MASS-WNV.
